Solution

The correct option is A $2 H_{2} S (g) + 3 O_{2} (g) \to 2 H_{2} O (l) + 2 S O_{2} (g)$
Hydrogen sulphide is slightly heavier than air; a mixture of $H_{2} S$ and air is explosive. Hydrogen sulphide and oxygen burn with a blue flame to form sulfur dioxide $(S O_{2})$ and water.

$2 H_{2} S (g) + 3 O_{2} (g) \to 2 H_{2} O (l) + 2 S O_{2} (g)$

Hence, option A is correct
